BT Versatility

It has modular construction allowing a basic setup to be expanded as needed by clipping extra modules onto a backplane

The basic Central Control Unit (CCU) starts off as a 8 extension unit, with either analog POTS lines or ISDN line modules available. There is a serial connection that can be used for call logging and configuration. It can either use standard telephones or proprietary feature phones. A special Door Phone may be added on extension 23 and the system may be connected to an electronic lock relay to allow the door to be opened via a Door Phone call. Any extension may be programmed as a PA (Public Address) speaker.

CCU backplane

Purchasing one of these allows up to 5 of the following modules to be added:

Ports module

Gives 8 more extensions by default and allows either:

ISDN BRI module (x2)

or a 2-Line POTS Module (x2)

Options module

This allows a Central Bell and Music On-Hold as well as an external Long-Line extension (up to 2Km).

BroadBand module
